"I went in to see him and just said, 'If you are not going to play me, it might be better for me to move on'," Rooney reveals.

"Then, all of a sudden, it was all over the press that I had put a transfer request in, which I never did.

"I don't know what happened and why that came out that way."

While Rooney admits he did not always see eye to eye with Ferguson, he hails the Scot as "the best manager of all time" and says he was the reason behind his move from Everton to Manchester United in 2004.

The 29-year-old opens up about the 2006 World Cup in the film, conceding that he was not fit enough after fracturing a metatarsal bone in his right foot six weeks before the tournament.

"Before the World Cup in Germany I broke my foot at Chelsea," Rooney says.

"You could feel the excitement building around the World Cup and it was touch and go as to whether I would be fit. And then Sven (-Goran Eriksson) put me in the squad.

"Looking back, if I could have gone back in time, then I probably would have sat out the World Cup. It was a big ask to get fit after six weeks out; I was never going to have that match sharpness."

Rooney was sent off during the quarter-final against Portugal after stamping on Ricardo Carvalho in an incident which featured then-Manchester United team-mate Cristiano Ronaldo.

Ronaldo, who pleaded with the referee to show Rooney a red card, insists the pair continued to be friends in the aftermath and even hints at a reunion in the future.

"We won every trophy together," the Real Madrid forward says in the film. "He's a fantastic boy and he helped me a lot.

"It was amazing to play with him. But the future, nobody knows, maybe we will play one day together again."

Also in the documentary, Rooney concedes he was "stupid" for shouting down a TV camera after England were booed off following a goalless draw against Algeria in the 2010 World Cup, while revealing he wooed Coleen with poetry in the early days of their relationship.
